Abstract Aroma (volatile) compounds play important ecological functions in plants, and also contribute to the quality of plant-derived foods. Moreover, chiral aroma compounds affect their functions in plants and lead to different flavor quality properties. Formations of chiral aroma compounds are due to the presence of enzymes producing these compounds in plants, which are generally involved in the final biosynthetic step of the aroma compounds. Here, we review recent progress in research on the plant-derived enzymes producing chiral aroma compounds, and their changes in response to environmental factors. The chiral aroma enzymes that have been reported produce (R)-linalool, (S)-linalool, (R)-limonene, and… More >

Abstract Citral (Eo) exhibits excellent fungicidal activities. However, it is difficult to maintain long-term fungicidal activity due to its strong volatility. Herein, a controlled-release strategy by using biomass-derived porous carbon (BC) was developed to overcome the drawback of Eo. New composite materials were prepared by loading Eo on tea stem porous carbon (BC@Eo), and their controlled-release fungicidal activity against Exobasidium vexans was assessed. BC with a large specific surface area of 1001.6 m²/g and mesoporous structure was fabricated through carbonization temperature of 700°C. The BC@Eo materials were characterized using Fourier-transform infrared spectroscopy and X-ray powder diffraction. The results suggested that chemical… More > Graphic Abstract
